Abstract

La présente invention concerne un procédé de charge rapide, un terminal mobile (300) et un adaptateur de source de puissance (400). Le procédé consiste : à envoyer, par un terminal mobile (300), une première instruction à un adaptateur de source de puissance (400) par l'intermédiaire d'une ligne de données dans une interface USB, la première instruction étant utilisée pour donner comme instruction à l'adaptateur de source d'énergie (400) de démarrer un mode de charge rapide ; et à recevoir, au moyen du terminal mobile (300), un courant de charge correspondant au mode de charge rapide provenant de l'adaptateur de source de puissance (400) de manière à charger une batterie dans le terminal mobile (300). Au lieu d'augmenter aveuglément un courant de sortie pour effectuer une charge rapide, l'adaptateur de source de puissance (400) effectue une charge rapide sur le terminal mobile (300) à l'aide d'un mode de charge rapide après réception d'une première instruction du terminal mobile (300), améliorant ainsi la sécurité du processus de charge rapide.
